<span>Since he was 30 flower pots and puts 10 in each, you would need to multiply 30 by 10 which leads to 300 seeds.</span>

He planted 300 because of the fact that he planted 10 seeds in each pot, and there's 30, so it would be 10*30 to find how many seeds he planted.

A chef has 10 spice jars, but his new spice rack only holds 8 spice jars. How many ways can he arrange 8 jars on the spice rack?

He has 10 spice jars, but the spice rack only holds 8 spice jars.
Calculate in how many ways he can choose 8 spice jars from 10 spice jars using combination:
$_{10} C _8=\frac{10!}{8!(10-8)!}=\frac{10!}{8! \times 2!}$

Each combination of 8 spice jars that he chooses he can arrange in 8! ways.

He can choose 8 spice jars in (10!)/(8!×2!) ways and arrange each combination in 8! ways.
Using the rule of product:
$8! \times \frac{10!}{8! \times 2!}=\frac{10!}{2!}=\frac{2 \times 3 \times 4 \times 5 \times 6 \times 7 \times 8 \times 9 \times 10}{2}=1814400$

He can arrange 8 jars on the spice rack in c. 1,814,400 ways.

∆ABC is reflected across the x-axis, then rotated 90° clockwise about the origin, and finally reflected across the line y = x to

torisob [31]

Answer:

Step-by-step explanation:

Notice that the vertices are A(1,1), B(2,3) and C(2,1).

A reflection across the x-axis give the coordinates A'(1,-1), B'(2,-3) and C'(2,-1). Then, we apply the rotation 90° clockwise about the origin A'(1,1), B'(3, 2) and C'(1, 2).

Finally, a reflection across the line y = x, gives A'(1,1), B'(2,3) and C'(2,1)

Therefore, the coordinates of the image are A'(1,1), B'(2,3) and C'(2,1).
